SECURING MEANS FOR THE COVERS OF DISPLAY-PACKAGES.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed May 7, 1915. Serial No. 26,550.

To all whom it may concern:

Be it known that I, THEODORE J. ABELE, citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Securing Means for theCovers of Display-Packages; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which is appertains to make and usethe same.

This invention relates to means for securing a transparent plate to thelid or cover of a display package.

The object of the invention is to provide a very simple, cheap andeflicient fastening device for holding a transparent plate upon theopening of the cover of a display packa e.

Another object is to provide a fastening device for the purposementioned which can be easily and quickly placed in position or removedto release the said plate.

In order to make the invention clearly understood, I have provided theaccompanying drawing, in which,

Figure 1 is a plan of the inner side of a display cover showing atransparent plate and fastening device therefor forming the subject ofmy invention. Fig. 2 is a sectional elevation of the same 'shown in itsinverted position. Fig. 3 is a sectional elevation of a portion of thecover and its transparent plate showing the invention on a much largerscale than in the first two figures; and, Fig. 4 shows the invention inperspective mounted upon part of a lid illustrating the manner ofengaging the transparent plate.

A represents a lid or cover for a box, barrel, or other form of package,and provided with a central opening B through which the contents of thepackage covered by the lid may be observed, and G represents thetransparent plate or glass plate covering said opening.

D indicates a series of U-shaped members soldered or otherwise securedto the inner surface of the lid or cover, the same bein spaced from oneanother substantially as shown. They are also spaced from the opening Ba sufficient distance to permit the transparent plate C to lie upon saidinner surface of the lid or cover. Said members D are preferablyextended slightly below the will just slip over lower surface of thesaid transparent plate as shown in F ig. 3 in which the lid or cover isinverted, though the extent of projection of the member is not highlyimportant.

E indicates a strip of thin sheet metal such as steel, or spring brass,having one of its extremities recurved upon itself as indicated at F,the same being slightly bent away from the body of the strip as shown inthe figure last referred to leaving a gradually widening space betweenit and said body, and secured to the latter by a rivet E. The oppositeend of the strip E is bent substantially at right angles into the part Gor-at a slightly acute angle to the bod thereof. The strip thus formedconstitutes the fastening device for the transparent plate, its endhaving the recurved portion F adapted to rest upon and firmly engage themargin of the plate and hold it upon the cover A. As shown, the saidportion F is adapted to engage beneath the U-shaped member, the latterlying between said portion and the body portion E, the rivet forming astop or abutment for said member D. The width of the part D is such thatwhen the strip is forced upon it as described and the rivet lies againstone edge, the part G and snap upon and lock with the opposite edge ofsaid member D, engaging beneath it in such a way that the strip will befirmly and securely held regardless of the weight of the transparentplate upon it when inverted upon the pack age, and regardless of anyheavy pressure or jars or blows of the most severe nature. The reasonfor this secure holding of the plate is that the recurved extension Facts as a fulcrum upon the inner surface or corner of the member D.Pressure, therefore, upon the lever formed outward from the said memberby the extension of the strip E and its recurved portion forces theopposite end having the part G, down upon the said member D, therecurved portion being unable, of course, to leave the latter.

The material of the spring strip is preferably quite stiff so it isrequired that the g .part G in order to be locked behind said member Dmust be given a strong sharp pressure to lock it in place so that itsfirm position is assured. Other means equivalent to the member D may beprovided for re ceiving the spring strip E such as will accomplish thedesired result since it is not FFTQE,

FLEXIBLE PIPE JOINT OR COUPLING.

Application filed June 20, 1913.

To all whom it may concern: Q

Be it known that I, EZRA C1 ALE, acitizen of the United States, residingat Tyrone, in the county of Blair and State of Pennsylvania, haveinvented certain new and useful Improvements in Flexible Pipe Joints orCouplings, of which the following is a specification.

My invention relates to flexible pipe joints or couplings for use inconnection with railway air brake systems.

The prime object of this invention is to provide a strong, durable,economical and efficient device designed to enable the con nected partsto move freely one relatively to the other, and at the same timepreventing the escape of the fluid passing through them.

Another object of the invention is to furnish a device constructed ofsuch material as will safely withstand the considerable pressure underwhich the air is passed through the pipes, thus preventing accidents andloss of life sometimes occasioned by the bursting of the air hose madeof rubber and fabric and commonly employed in air brake systems, and hasspecial reference to pipe installations on railway trains, where theconnected parts are subjected to frequent relative movements.

The foregoing and such other objects as may occur from the ensuingdescription are attained by the combination and arrangement of partshereinafter more fully described, and particularly set forth in theclaim appended hereto, and illustrated in the accompanying drawings, inwhich 2- Figure 1, is a view partly in plan and partly in perspectiveshowing the device embodying my invention. Fig. 2, is a longitudinalsectional view of my improved flexible joint, and Fig. 3, is a plan viewshowing the parts constituting one of the members detached from itsconnection.

Similar characters of reference indicate like parts in all the figuresof the drawing.

The several parts employed in carrying out my invention are made of anysuitable metal best adapted to withstand the air pressure to which theparts are necessarily subjected, and consist of the sections or membersA and B, each of said sections or members being movably connected to ahollow central member or casting O.

The section or member A is composed of two hollow metallic pipe castings1 and 1 Specification of Letters Patent.

each being curved inward and terminating at its outer end with astraight extension 2, the inner face of each extension being made tocontact with each other and tightly secured together by a sleeve or band3, or in any suitable manner, while the inner end of each of saidcastings terminates in a lateral or inward extension 5 adapted to berotatably connected to the lateral extensions 5' forming a part of saidcentral member C. The section or member B of my improved flexible jointis likewise constructed of castings 6 and 6 in all respects like thesection A, and the inner end of each of said castings 6 and 6 are fittedto lateral extensions on member C formed at right angle and adj acent tothe said extensions 5. The central member 0 consists of a single castingcomprising, a hollow central hub portion 7 provided with shoulders 4.,said hub portion having reduced hollow integral lateral extensions 5projecting from either side thereof, and also reduced hollow integrallateral extensions projecting from either side of said hub portionadjacent to and at right angles to the said extensions 5, the inwardlateral extensions of each member A and B being adapted to abut againstand rest in contact with the said shoulders 4 formed on the hub. Themetallic pipe castings 1,1, and 6, 6 are each curved inward andterminate at each outer end with a straight extension 2, and by placingthem together an inlet passage 8 is formed in member A, and an outletpassage 12 is formed in member B.

It will readily be seen that air or fluid passing into the opening 8 insection A will pass around through the openings in 1 and 1 and into theopening 9 in the central member, and from thence through the crossopening 10, and thence through the openings 11 formed in the castings 6and 6 and out through opening 12 in section B, at whatever angle thesections A and B may be placed with respect to each other.

It will be readily perceived that by connecting the sections to thecentral member in the manner herein described and as illustrated in thedrawings the said sections will move freely one relatively to the otherto -the right or left, or in an upward or downward direction.

It will be obvious that my improved flexible coupling may be connectedin any suitable manner to the train pipe system, and that any old andwell known type of car
